Since selling my safetyshoesreviews website I have cleared another slot in my inventory.
Right now I have started https://www.scalextriclab.com together with an Indian buddy of mine. He provides the content that I then review, adapt to make it SEO friendly and do the off-page SEO.
So far we have had one click already coming from Facebook to our site since posting our first article yesterday.
I estimate that the value of this niche site will reach close to $3k especially when you take the Christmas season into account!
